Overall Equipment Effectiveness (OEE) is a powerful metric of manufacturing performance incorporating measures of the utilization, yield and efficiency of a given process, machine or manufacturing line. Three measurable components: Performance Rate (PR), Quality Rate (QR) and Availability (A) are working together to achieve an OEE and their combinations in each period are always different. The best tool to evaluate the contribution of these components or contributors is the Shapley value, proposed by Lloyd Shapley. This paper estimates how each component has contributed to OEE at a decided period, and estimates during which period the activity was best performed and the best contributed component using the Shapley value in a continues process industry.
